The NFL will eliminate some restrictions from its current COVID-19 protocols for players who choose to be vaccinated. 

Among the elements that could be eliminated are the need to participate in daily testing; quarantine periods due to close contact with an infected individual; and/or refraining from social gatherings among other vaccinated individuals.

"It is also anticipated that clubs that achieve a certain rate of vaccination among its tiered staff and players may be permitted to relax restrictions that apply to meetings, meal time and use of locker rooms," the memo said.

NFL Players Association president JC Tretter argued again on Wednesday that the coronavirus-caused elimination of such things as organized team activities (OTAs) and minicamps did more good than harm in 2020.

"The good news for our sport is that while the NFL season looked and felt noticeably different from previous years,'' the Cleveland Browns center posted on the union's website, "we learned that the game of football did not suffer at the expense of protecting its players more than ever before. Our process is to follow the science on what is safest for our guys, and many of the changes this past year -- like no in-person offseason workouts/practices, the extended acclimation period before training camp and no preseason games -- gave us a year of data that demonstrates maintaining some of these changes long term is in the best interest of the game.''
